JOHN FRANCIS HERO, OF NEWARK. OHIO- ILUE TURNING AND READING TOOL.

Specification of Letters Patent. Application Med April 10, 1811.

Patented Feb. 6, 1.912. Serial No. 620,080.

To all whom it may concern:

Be it known that I, Jonx F. Geno, a citizen of the United States. residing at Newark, in the county of Licking and State of Ohio. have invented certain new and useful Improvements in Flue Turning and Beading Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

This invention relates to tools for operating upon fines, and more particularly to a combined turning and beading tool for fines of different diameters.

An object of the invention is to combine the turning and bending tools, making one tool for the two pur oses and enabling the workman to turn an bend a fine with one operation of the single tool.

Another ob'ect is to devise a tool which will serve as 0th a flue turning tool and a fine beading tool and which will therefore both turn and bend the fiue in one operation in about half the time now required to turn the flue with a fine turning tool and then bend the flue with a flue beading tool, making two separate operations, and,

A further ObJtCt is to provide a tool of the above stated character which will be extremely simple in construction and operation and which will be easy and cheap to manufacture.

Other objects and advantages will be hereinafter set forth and pointed out in the specification and claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a view of the tool ap died to one end of a flue to turn and bead t lc latter. Fig. 2 is a plan view at right angles to Fig. l. the tool being removed from the end of the flue, Fig. 3 is an end view of the tool. looking at the rounded end thereof. and, Fig. 4 is an end view of the same, looking at the workin end of the tool.

Tleferring to the drawings in which similar reference numerals designate corresponding parts throughout the several views. the tool consists of the rounded shank portion 1 and the octagonal shaped central portion 2, from which extends the tint beveled sides 3 of the turning and heading end of the tool.

At right angles to the tint beveled sides 3 are the slightly flared sides 4, one of the sides 4 extending beyond the opposite side 4, the purpose of which will presently appear.

The beveled sides 3 converge to within about three-eighths of an inch at their outer extremities. while the sides 4 are about one inch apart at their outer extremities. thus forming a working or line engaging end of about three-eighths of an inch thick and about one inch wide. The dimensions, however, may be varied as desired, but it is preferred to have the proportions about the same as just described.

From the short side 4 the flue engaging end is straight and directed at an angc to the side 4 for a short distance, as shown at 5. From the inner edge of the portion 5 the flue engaging end is directed inwardlv and curred in semicircular form, to )rovide the flue end receiving recess 6, an from the portion 6 the engaging edge is curved ontwardly to present the curved flue entering portion 7, which connects with the long side 4 of the working end of the tool. Thus. it will be seen that the working end of the tool is provided with a straight ortion 5 connected with the short end 4 and directed at an angle thereto. a central semicircular nick or flue end receiving recess 6 connected with the straight portion 5. and. beginning at this point and also connected with the outward v curved flue entering or convex portion which connects with the long straight edge 4. The shank 1 is adapted to be engage with a pneumatic hammer, as will be understood.

The operation of the tool is as follows: The working end of the tool is placed against the end of the flue to he turned and headed. in such position that the edge of the flue rests within the semicircular nick 6. the straight portion 5 being outside of the flue. while the long curved ortion 7 is within the flue. The tool. as will be understood, is held by the operator. in the proper position and. while held in this position. is caused by the pneumatic hammer. to pound upon the end of the line to turn and bend the same. As the tool is held in this position and forced against the heated and of tho the working and of the tool will, by being held roperly. curve the edge of the line outwart ly and, the sharp edge, at the junction of the straight portion 5 and semicircular portion t will force the edge of the line, as it is turned or curved against the boiler head and form the. end into a head, making a water tight connection between the boiler head and the turned and headed end of the line.

It will be understood that the tool is moved around the edge of the line end. turning and bending the end gradually. On account of the strai ht. portion 5 of the working end of the tool heing directed at. an angle of more than 90. the end of the line, as it is forced by the tool to turn outwardly, will be )rcssed tightly a ainst the boiler head and. thus, the bead wi i be formed out of the end of the line, as the latter is turned, accomplishin two resnlts with one operation of one too This, it will be seen, eliminates the necessity of first turning the end of the fine with one tool and then beading the tine with a second tool, requiring two separate operations and a double amount of time as well as labor.

Thus, it will be seen that my combined flue turning and beading tool eliminates the necessity of having separate tools for these two operations, and also saves the double labor and makes it ossible to perform this work in one-half t 1e time heretofore required, cutting the expense of such work in half as well as the price of the implements necessary.

This tool may be eflectively used for turning and beading the ends of either cold or heated fines of various diameters.

It. will be readily seen that as the working end of the tool is of substantially rectangular form in cross section and only about threeeighths as wide across the flue end receiving recess, or nick, as the width at right. angles thereto, or from one straight edge 4 to the other straight. edge 4, there will only be an extremely small portion of the edge of the due engaged at. one time. Thus, the force or power will be concentrated and applied directly to only an extremely small portion at one time. the tool being moved around the edge of the flue as the latter is turned and headed in the one operation. Owing to the culiar construction of the working end of this tool, the same may be effectively used for turning and heading the ends of lines of various diameters. eliminating the necessity at duplicating the ditl'erent sizes for the lines of diti'erent diameters, as is-now necessary with the so mratc tluc turning tools and tlue beading too s in general use.

In operation the tool is preferably held in the position shown in Fig. l (in divert alinement with the flue) and driven straight forward, the curvature of the working and of the tool ro wrly turning and heading the cd e of t it. line as the tool is moved around said edge. It will be evident. however, that if desired, the tool may be held at, various angles during the operation, the same as the tools now in use, but this is not at all necessary.

It will be evident that with this tool, which enables the concentration of the power and force to only a small portion of the edge of the line at one time, the work will be much more ell'ective and more readily accomplished than is now possible with the present form of line turning tools and lluc beading tools which engage the entire end of the line at one time.

What I claim is:

l. A tool for turning and heading a line, comprising a shank portion, a central portion integral with said shank portion, a working cud integral with said central portion opposite said shank ortion, said working portion having opposite converging beveled sides and o posite arailel strai ht sides atright nu l; es to said beveled sides, one of said straig it sides being shorter than the opposite straight side, said working ortion aving a flue-enga ing end with which said sides connect, said flue-engaging end having a semicircular flue-receiving recess, an outwardly curved flue entering portion connecting with said semicircular recess and the lon straight side of said working end, and a short straight portion for said engaging end connecting with the semicircular recess and with the short straight side, said straight portion being at an angle to said short strai ht side.

2. A too for turning and beading a line, comprising a shank portion, a central portion integral with said shank portion, a

integral with said central perworking end tion opposite said shank ortion, said working portion having opposite converging beveled sides and o posite parallel straight sides at. right ang es to said beveled sides, one of said straight sides being shorter than the opposite straight side, said working ortion having a flue-engagin end with w iich said sides connect, said tie-engaging end having a semicircular flue receiving recess, and an outwardly curved line entering portion connecting with said semicircular recess and the long straight. side of the working end. said short straight edge being at a great angle. to the said short side.
